Rated 5 out of 5 by from Can't find anyting better than Science Diet! My husband sold Science Diet in his veterinary office for many years and animals that ate SD were by far healthier than generic eaters. If you care for your pet you're going to spend money on them one way or another - either on good food or in the vet office. Our four cats love it!

Rated 5 out of 5 by from Fantastic Stepping Stone As You Bring Your Kitties to No-Grain ! We rescued ferals in our general neighborhood for years. We would graduate them from the most tasty yet least pricey grain-laden (because we were not educated in feline nutrition) kibble to this brand once they decided we had finally tamed down enough for them to live with us. As applicable for their age, they, eventually had this particular kibble in their bowl. It is their early years comfort food. They don't eat much of it anymore but do like having it available. They sort of treat it like a granola bar that is already crumbled up for them, though the hard round pellets do offer them a challenge. They do have to slow down when they eat it or they end up tossing their cookies. By the way, this brand also offers a no grain kibble. Just saying, had I a do over opportunity, I would have gone with the no grain right from the start. And, yes, most likely, have chosen this particular brand. Enjoy! Love Those Felines of Yours! You are All Worthy !

Rated 5 out of 5 by from Science Diet for cats I purchased this food for our feral cat that has adopted us. Even though it is a bit expensive, I know Science Diet is a great brand. Our vet toured their plant and highly recommends their products.

Rated 5 out of 5 by from Easy transition from Science Diet Kitten Formula When I rescued my seal point Siamese from the shelter and took him to the vet for his first visit, they gave me a bag of free goodies, one of which was Science Diet. I used the kitten formula until he was one year and transitioned him to the adult without a single complaint. My last cat of 15 years was on Science Diet and, as in this instance, he readily ate 'special' diets when he was ill, and the senior diet in his senior years. I have only ever used Science Diet with my pets and recommend it to others.

Rated 5 out of 5 by from Best of many possibilities. Good product. Good price. Good service. Feeding 5 Newfoundland dogs & 2 cats so what they offer is very important. Only wish they would provide rewards or coupons for frequent buyers. Will continue to use as long as the above remains the same.

Rated 4 out of 5 by from My cat likes this particular brand which is hard to find. Ordered two large bags late afternoon on a Thursday and the bags were delivered late Friday morning. Excellent service, no shipping charges. Extensive selection of pet food, my cat happens to like this particular brand which is not carried in most markets. I will definitely use Chewy again and recommend it.

Rated 5 out of 5 by from Satisfies my cats I was feeding another brand of cat food. My cats were constantly wanting to be fed and acting as if they were not ever satisfied. I began to wonder if they were not getting enough nutrition. After reading the labels at my local store I noticed chicken was the first ingredient in this cat food. Now they eat less and I am not actually out more money even though this food is quite a bit more expensive.

Rated 5 out of 5 by from So worth the price! Our young cat was recently diagnosed with FeLV. The vet said in order for him to have any chance at living very long he would need optimum care, including a high protein quality food. Hills meets that need and Sammie really loves it. He is maintaining a good weight and staying healthy so far. Thank you so much for supplying quality pet foods at affordable prices!

Rated 5 out of 5 by from The litter box dont smell!! That is what I really love about it! And it takes very little to fill them up. I feed all five of my cats and the feral cats the same thing...it makes them look so pretty, I have the best looking feral cats in the neighborhood!

Rated 5 out of 5 by from Provides optimal nutrition, and my cat actually eats it! My daughter, who lives out of state, recommends Hills Science Diet, and the shelter from which we adopted our cat feeds it to its animals, so Zumi was already eating it when we brought her home. She especially LOVES the canned salmon for ages 1-6.

Rated 1 out of 5 by from My cats won't eat it. My cats are used to the Indoor Adult Hill's Science Diet, and did not like the optimal care. I guess I'll have to donate it to the animal shelter.
